Kostochondryt
Etiologia i przyczyny

Kostochondryt to zapalenie chrząstki łączącej żebra z mostkiem, o etiologii najczęściej idiopatycznej, choć zidentyfikowano liczne czynniki predysponujące. Do najważniejszych należą powtarzające się mikrourazy połączeń żebrowo-mostkowych, bezpośrednie urazy klatki piersiowej (np. wypadki, urazy sportowe, resuscytacja), infekcje wirusowe (w tym po COVID-19) oraz bakteryjne (Staphylococcus aureus, Actinomyces, Salmonella, Escherichia coli) i grzybicze (Candida albicans, Aspergillus). Schorzenie współwystępuje także z chorobami reumatycznymi (RZS, ZZSK, łuszczycowe zapalenie stawów), fibromialgią, chorobami zapalnymi jelit oraz osteoartrozą. Czynniki anatomiczne i posturalne, takie jak skolioza, niewłaściwa postawa, wiązanie klatki piersiowej, a także przewlekła astma, zwiększają ryzyko rozwoju kostochondrytu.

Etiologia kostochondrytu

Kostochondryt (łac. costochondritis) to schorzenie charakteryzujące się zapaleniem chrząstki łączącej żebra z mostkiem (połączenia żebrowo-mostkowe). Dokładna przyczyna tego stanu zapalnego nie jest w pełni poznana, a w większości przypadków etiologia pozostaje idiopatyczna, czyli nieznana 123. Pomimo braku jednoznacznej przyczyny, naukowcy zidentyfikowali szereg czynników, które mogą prowadzić do rozwoju tego schorzenia.

Mikrourazy jako główna przyczyna

Wielu ekspertów uważa, że kostochondryt jest wynikiem powtarzających się drobnych urazów (mikrourazów) połączeń żebrowo-mostkowych, które z czasem prowadzą do stanu zapalnego 45. Do czynników powodujących mikrourazy należą:

  • Powtarzające się ruchy górnej części ciała, szczególnie te angażujące klatkę piersiową 67
  • Intensywne treningi fizyczne lub nagłe zwiększenie intensywności ćwiczeń 89
  • Dźwiganie ciężkich przedmiotów 1011
  • Intensywny kaszel lub wymioty 1213

Urazy bezpośrednie

Bezpośrednie urazy klatki piersiowej stanowią znaczący czynnik ryzyka rozwoju kostochondrytu 1415. Mogą one wystąpić w wyniku:

  • Wypadków komunikacyjnych 16
  • Upadków 17
  • Urazów sportowych, szczególnie w sportach kontaktowych 1819
  • Procedur resuscytacyjnych (RKO) 20

Infekcje jako czynnik wywołujący

Infekcje różnego pochodzenia mogą prowadzić do rozwoju kostochondrytu 2122:

Infekcje wirusowe

Wirusowe infekcje dróg oddechowych mogą wywoływać kostochondryt zarówno poprzez bezpośredni stan zapalny, jak i pośrednio przez wywoływanie intensywnego kaszlu 2324. Opisywano również przypadki kostochondrytu po zakażeniu COVID-19 2526.

Infekcje bakteryjne

Infekcyjny kostochondryt bakteryjny występuje rzadziej i dotyczy głównie osób po operacjach klatki piersiowej lub zażywających dożylnie narkotyki 2728. Najczęstszymi patogenami są Staphylococcus aureus, Actinomyces, Salmonella oraz Escherichia coli 2930.

Infekcje grzybicze

Zakażenia grzybami takimi jak Candida albicans i Aspergillus są rzadszą przyczyną kostochondrytu 3132. Częściej występują u osób z obniżoną odpornością lub po zabiegach kardiochirurgicznych 33.

Choroby współistniejące

Kostochondryt może występować jako objaw towarzyszący innym schorzeniom zapalnym 3435:

Czynniki anatomiczne i posturalne

Nieprawidłowości anatomiczne i posturalne mogą predysponować do wystąpienia kostochondrytu 42:

  • Skolioza i inne deformacje klatki piersiowej 4344
  • Niewłaściwa postawa ciała („iHunch”), szczególnie długotrwałe pochylanie się nad urządzeniami mobilnymi 4546
  • Wiązanie klatki piersiowej (chest binding) stosowane przez osoby transseksualne 4748
  • Chroniczna astma, wpływająca na mechanikę oddychania 49

Inne czynniki ryzyka

Zidentyfikowano również inne czynniki zwiększające ryzyko wystąpienia kostochondrytu 5051:

  • Wiek: najczęściej występuje u osób w wieku 40-50 lat 52
  • Płeć: częściej diagnozowany u kobiet 53
  • Niedobór witaminy D: opisano przypadki kostochondrytu, które ustąpiły po suplementacji witaminy D 5455
  • Ciąża: zwiększony nacisk na klatkę piersiową podczas wzrostu płodu 56
  • Zabiegi chirurgiczne klatki piersiowej: szczególnie torakotomie i operacje z rozdzieleniem mostka 57
  • Duży biust: może zwiększać napięcie na połączeniach żebrowo-mostkowych 58

Mechanizmy patofizjologiczne

Dokładny mechanizm patofizjologiczny kostochondrytu nie jest w pełni poznany. Proponowane mechanizmy obejmują 5960:

  • Zapalenie neurogenne
  • Zaburzenia równowagi mięśniowej
  • Neuropatia nerwów międzyżebrowych
  • Ból mięśniowo-powięziowy
  • Dysfunkcja mechaniczna połączeń żebrowo-mostkowych

Szczególnie istotna wydaje się teoria dotycząca kompensacyjnego przeciążenia stawów żebrowo-mostkowych w wyniku ograniczonej ruchomości stawów żebrowo-kręgowych. Gdy stawy żebrowe w tylnej części klatki piersiowej ulegają ograniczeniu ruchomości, bardziej delikatne połączenia żebrowo-mostkowe muszą kompensacyjnie zwiększyć swoją ruchomość, co prowadzi do ich przeciążenia i rozwoju stanu zapalnego 61.

Czynniki etiologiczne kostochondrytu – podsumowanie

Kostochondryt jest schorzeniem o złożonej i często trudnej do określenia etiologii. W większości przypadków jest to stan idiopatyczny, jednak zidentyfikowano szereg czynników przyczyniających się do jego rozwoju 6263. Najczęściej wymieniane przyczyny obejmują powtarzające się mikrourazy, bezpośrednie urazy klatki piersiowej, infekcje, choroby współistniejące oraz nieprawidłowości anatomiczne i posturalne 6465.

Zrozumienie wieloczynnikowej etiologii kostochondrytu jest kluczowe dla właściwego podejścia diagnostycznego i terapeutycznego. Uwzględnienie możliwych czynników przyczyniających się do rozwoju choroby pozwala na bardziej precyzyjne leczenie i wprowadzenie odpowiednich modyfikacji stylu życia, które mogą zmniejszyć ryzyko nawrotów 66.

    Much coughing delivers a surprisingly strong percussive impact to all the rib cage joints. If the rib cage is already sufficiently tight around the back before coughing starts, then only the more delicate sternocostal rib joints on the breastbone can give (and strain) to take the shock. This is well known as a trigger for costochondritis from pneumonia, bronchitis, the flu, or even just a bad cold. More recently there have been indications of a tsunami of fresh costo outside NZ after coughing and/or rib cage muscle spasm with COVID-19. This is from the same mechanism – it is not a special feature of the coronavirus. The many reports of costo triggered by Covid-19 vaccinations (usually Pfizer) are probably from the normal and intended body response to a vaccine, which includes an inflammatory response. If the rib cage is already tight enough, with the rib cage joints on the breastbone already straining, then the extra lift in general inflammation can be enough to trigger them into symptomatic costochondritis. Note that once the costochondritis has been triggered, it can continue even though the coughing and infection has passed – for as long as the rib machinery around the back driving the ongoing strain at the rib joints on the breastbone stays frozen and immobile.

Costochondritis may follow surgical procedures involving the chest wall or esophagus, or after repetitive and/or sudden movements involving the rib cage and upper extremities. In particular, aspergillus costochondritis has been associated with coronary artery bypass grafting. Rare case series of candida costochondritis have become more prevalent with the rise of intravenous drug use. Another rising cause of Candida and Staphylococcus costochondritis has been related to COVID-19 infection treatment. […] Environmental allergies that predispose to repeated sneezing or coughing may increase the risk of developing costochondritis.

    Costochondritis is a condition characterised by inflammation of the cartilage that connects the ribs to the breastbone (sternum), known as the costosternal joint. […] Although the exact cause of this inflammation is often unknown, costochondritis frequently affects individuals involved in physical activities or those who have recently experienced trauma to the chest area. It can also be linked to certain medical conditions or infections. […] Several potential causes and contributing factors include: Physical Strain or Trauma: Activities that involve repetitive chest movement, heavy lifting, or strenuous upper body exercises can place stress on the costosternal joint. Direct trauma to the chest, such as from a fall or impact, can also lead to costochondritis. Inflammatory Conditions: Conditions such as arthritis or ankylosing spondylitis can contribute to the development of costochondritis by causing generalised inflammation in the joints and connective tissues. Respiratory Infections: Viral or bacterial infections, particularly those affecting the respiratory system, may cause inflammation in the rib cartilage. Persistent coughing from these infections can also strain the chest, leading to costochondritis. Fibromyalgia: Individuals with fibromyalgia, a chronic pain disorder, may experience costochondritis as part of their symptoms. The chest pain associated with fibromyalgia is often attributed to costochondritis. Poor Posture: Maintaining poor posture, particularly during long periods of sitting, can place extra pressure on the chest and rib cage, potentially leading to inflammation.
